Abstract

A method of inhibiting corrosion and the formation and deposition of scale and iron oxide in aqueous systems comprises adding to the system at least 0.1 ppm of a water-soluble polymer having an intrinsic viscosity of 0.05 to 2.5 dl/g, prepared from: (a) 35 to 90% by weight of an unsaturated carboxylic acid or its salt; and (b) 5 to 40% by weight of an unsaturated sulfonic acid or its salt; and (c) 5 to 40% by weight of an unsaturated polyalkylene oxide compound. A novel water soluble polymer having an intrinsic viscosity of 0.05 to 2.5 dl/g is prepared from: (a) 35 to 90% by weight of an unsaturated carboxylic compound that is acrylic acid, methacrylic acid, maleic acid, itaconic acid, a salt of such an acid or a mixture of two or more such compounds; (b) 5 to 40% by weight of an unsaturated sulfonic compound that is 2-acrylamido-2-methylpropylsulfonic acid, 2-methacrylamido-2-methylpropylsulfonc acid, methallylsulfonic acid, allylsulfonic acid, vinylsulfonic acid, styrenesulfonic acid; a salt of such an acid or a mixture ot two or more such compounds; and (c) 5 to 40% by weight of an unsaturated polyalkylene oxide compound.
